Abstract

In this paper, E-health is investigated due to its advantages such as reducing health care cost, saving time, and decreasing unnecessary going to a clinic or hospital. In this research oxygen saturation is chosen as a sample signal for E-health investigation, therefore an applicable method is introduced to calculate oxygen saturation and a package of pulse oximetry is designed to receive signal which is recorded and sampled by sound card of computer, by means of MATAB. The recorded data is sent to a doctor through internet, which can be demonstrated in spectra, prepared for further analysis and also a model for counting heart beats is proposed. The numerical results, which were gained in number of experiments by attending different volunteers, show its reliability. Proposed device of pulse oximetry is simple, portable, and just need a cable for connecting to a computer to send the data through internet for expert analysis.
